MT3503

MT3503 is a high-performance, ultra-low power optical navigation sensor with integrated digital image processing circuits. This chip is based on LASER optical navigation technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the speed, direction, and magnitude of motion. This tracking system does not require encoded pattern, encoded strip or any special marking on the tracking surface. The built-in current calibration and CPI calibration functions, suitable for high volume assembly, ensures consistency.
